Abstract

Measurements at Cape Grim, Tasmania, during the recent Southern Ocean
Photochemistry Experiment (SOAPEX-2), using a static Cloud
Condensation Nucleus (CCN) counter, show delayed growth in development of the peak in light scattering when sampling marine air. In polluted air the time taken to reach the peak in scattering is similar to that for the inorganic salts used to calibrate the counter.
